Hmmm...well, most of this website is sorta cyan-ish, so the compliment would be red. I like red. It's attention getting. And my car is red (mostly--Mazda calls it Copper Red and it's really more of a brick color).

I like #993300
It sorta matches my car and would be a great compliment to the color of the dark cyan font used in the header line that reads "User Groups "new activities" font color. (Read 12 times)"
I'm a shit.

'15 Goals:

I'll keep that color in mind. It's a nice rich red, but I'm not sure how that will look until I see it in action. It always happens. I finda nice soothing color in the color picker, and when I apply it, it turns out to be too strong, or just plain ugly. The new tabs took me HOURS! The shades weren't blending in with the other colors. They were too dark, too light, too bright, not enough contrast with the text. Ugh!
Anyway, have you seen this site:

It's quite good for finding colors.
